"A novel that feels like a puzzle . . . Olde Heuvelt deftly juggles many characters while delivering chapters full of supernatural mayhem. This is a novel that toys with the end of humanity, but the threshold to the apocalypse has seldom been so fun. This is Olde Heuvelt's sharpest, most compelling work to date."--The New York Times

"Cleverly takes the reader on a hard-to-predict path, which leads from haunted ship to thriller-like government shenanigans to some pretty bloody fights and an extended action sequence involving a helicopter and an oil rig. . . A compelling page-turner."--Wall Street Journal

"Told in the style of an international thriller and featuring a huge cast of well-developed characters, the novel is a deep dive into how the tendrils of the past can reach out and force humanity to heed a warning"--Library Journal

Praise for Thomas Olde Heuvelt

"The long-awaited new novel from the Dutch author of Hex is an ambitious, capacious work. . . containing everything from psychological suspense to cosmic horror. With moments of wonder as well as terror, it looks likely to be one of the highlights of this year's horror scene."--The Guardian, on Echo

"Horrific, poignant, creepy, brilliantly written--expect to see it on bestseller lists and year's end best lists, and hopefully awards consideration. Don't sleep on this one."--Jeff VanderMeer, on Echo

"Totally, brilliantly original."--Stephen King, on Hex

"Creepy and gripping and original." --George R.R. Martin, on Hex

"A touch of strangeness, of alienness, avoiding sub-Stephen King clichés. [Olde Heuvelt] has written five novels already, and publishers should be lining up to translate them."--The Wall Street Journal, on Hex

"One of the most original, clever, and terrifying books to be published in the 21st century."--New York Journal of Books, on Hex
